Definitions

  • the present invention relates to an organic render composition having improved properties and the use of such an organic render composition, in particular for exterior use on a building substrate like e.g. facades, walls or ceilings of a building.
  • Organic render compositions also called organic plaster compositions
  • organic binders which are building materials used for the protective and decorative coating of building substrates like e.g. facades, walls or ceilings of a building.
  • render compositions are factory-made and manufactured in paste form, ready to use, very seldom in powder form. I.e. the render or plaster composition is pre-mixed with water and ready to be applied as a workable paste to the building substrate.
  • organic render compositions should on the one hand have a long, extended processing time which allows the render to be structured respectively textured for a long time after the aqueous paste has been applied and before it properly dries and cures on the building substrate.
